Applicator Single-Use Indicator Flag DESCRIPTION/INDICATIONS FOR USE Description: The MIST Therapy System uses ultrasound technology to atomize saline and deliver it as a continuous mist to the treatment site. The mist generated has a relatively uniform droplet size that acts as a conduit for transmitting ultrasonic energy to the treatment site. Indications for use:The MIST Therapy System produces a low energy ultrasound-generated mist used to promote wound healing through wound cleansing and maintenance debridement by the removal of PL-61000 Rev. A, 12/09 yellow slough, fibrin, tissue exudates and bacteria. ©2009 Celleration , Inc. ® PREPARING THE PATIENT FOR TREATMENT WITH THE MIST THERAPY® SYSTEM • Depending on the wound location, position the patient in a comfortable position for treatment • Remove soiled dressings and discard all contaminated materials (gloves, dressings, pads) prior to a MIST Therapy treatment. • Use appropriate Infection Control Procedures throughout the treatment session • Treatment with the MIST Therapy System will require a clean environment. Clean the transducer (9) with the provided germicidal wipes prior to and after use. • Place an absorbent pad (included in separate applicator kit) under the portion of the patient being treated to collect the saline runoff. • Do not reuse applicator or save for future patient use. PREPARING THE MIST THERAPY SYSTEM 3 2 1 8 4 3 9 16 ? HELP SELECT 13 Remove the Applicator (8) from its package and press the Applicator (8) onto the Transducer (9) in one continuous motion, insuring the metal tip (13) is in the center of the Applicator (8). You should feel a click as the Applicator (8) is properly seated onto the Transducer (9). NOTE: Do not touch the Transducer Tip (13) at any time while the power is on. 4 Plug the Generator Power Cord (1) into an electrical outlet. Connect to a “Hospital Grade” or “Hospital Only” receptacle to achieve grounding reliability. Turn the Generator (2) “on” using the Power Switch (3) on the back of the Generator (2). Once “on”, you will hear a short tone as the Generator (2) performs a system check (approximately 10 seconds). If the screen (4) does not respond and remains dark, see Trouble-Shooting. When the Generator Screen (4) reads "Select Wound Size", you are ready to continue the setup process. NOTE: When placing the applicator onto the transducer, make sure the Saline Flow On/Off Indicator Arrow (16) and the “Off” Indicator Mark (17) are aligned, to ensure that saline does not flow when bottle is inserted in steps 5 and 6. 5 6 10 50ml 6 10 8 8 50ml 9 7 5 Place the Celleration MIST Therapy Saline Bottle (10) upright into the Applicator (8), using the Applicator walls as guidance. The "cup" opening and gradations on the bottle should be facing the Transducer (9). Engage the Celleration MIST Therapy Saline Bottle (10) using one forceful, downward thrust into the Applicator (8) to puncture the Celleration MIST Therapy Saline Bottle (10). Choose the wound size (cm2) by moving the Arrow Buttons (5) on the Generator (2) unit up or down. The corresponding treatment time for a given wound size will appear as well. The Applicator (8) is designed as a disposable unit to avoid contamination risk. Do not remove the Celleration MIST Therapy Saline Bottle (10) once engaged. Press Select Button (6) to lock in the correct treatment time. If the incorrect time is entered, use the Back Select Button (7) to alter the treatment time by using the Arrow Buttons (5) and then, pressing the Select Button (6). TREATMENT TIMES GREATER THAN SALINE BOTTLE CAN PROVIDE When treating wounds with areas of greater than 30 cm2 on the same patient, it will be necessary to refill the saline bottle approximately every five minutes or as required to fulfill a treatment. To refill, remove the cap (25) (the cap is scored for easy removal at the neck of the bottle) from the initial saline bottle that is already seated in the applicator assembly. If you know that you will be refilling for longer treatment times it is recommended that the cap be removed before starting the initial treatment. Refill the saline bottle from a second saline bottle (with just the tab removed). Multiple wounds on the same patient can be treated by refilling the saline bottle (10). Follow your local infection control procedures. Do not reuse applicator between patients or retain for future patient use. When treatment of a patient is complete, remove the applicator and discard. TREATING THE PATIENT WITH THE MIST THERAPY® SYSTEM NOTE: Treatment with the MIST Therapy System should occur shortly after preparation. Preparation of the system in advance of treatment may lead to saline loss if the applicator valve has been inadvertently opened. Follow infection control procedure per facility policies. 1 21 10 Hold the Treatment Head (11) (transducer and applicator assembly) firmly in one hand and gently twist off the Vent Tab (21) from the Celleration MIST Therapy Saline Bottle (10) by grasping the Vent Tab (21) and turning. Discard the Vent Tab. This will create a vent in the Celleration MIST Therapy Saline Bottle (10) and allow saline to flow upon completing step 2. Be sure not to turn the bottle and portion of the Applicator (8) holding the bottle at this time. PL-61000 Rev. A, 12/09 ©2009 Celleration®, Inc. 2 3 15 10 50ml 11 18 11 24 16 To initiate saline flow, turn Celleration MIST Therapy® Saline Bottle (10) and Applicator (8) in a counter clockwise motion until the “On” Indicator (18) on the applicator is aligned with the On/Off Arrow on the applicator (16). Allow the saline to flow through the applicator for 3-5 seconds. Do not let saline flow any longer than that or the saline will build up within the Applicator (8) and create an inconsistent therapeutic mist. 4 The Treatment Head (11) should be held so that it is perpendicular to the wound with the Leading Edge of Applicator (12) approximately 0.5 to 1.5 cm (0.2 - 0.6 inches) from the wound. You are now ready to begin treatment. Indicator (24) is solid green. Depress and release the Control Button (15) at the top of the Treatment Head (11). Indicator (24) is flashing green. You may pause treatment by pushing the Control Button (15) (now solid green) again and rotating the saline bottle to the off position. Never activate the transducer (11) without applicator (8) in place. 5 l 50m 11 4 0.5 - 1.5 cm 23 ? HELP (Spray Pattern) SELECT The MIST Therapy System will begin to deliver a continuous mist. Move the Treatment Head (11) vertically across the wound using multiple passes. Follow this by moving the Treatment Head (11) horizontally across the wound using multiple passes. The Treatment Head (11) should be moved in front of the wound using slow, even strokes and should not be waved in a swinging fashion. The distance between the Treatment Head and wound can be varied as well between the 0.5 to 1.5 cm (0.2 - 0.6 inches) during treatment. Audible and visual bubbling may occur. This is normal when moving back and forth through the recommended treatment range. Continue treatment (ACTIVE) until you hear three long tones and the Generator Screen (4) returns to the Select Treatment Time mode. Once the treatment is completed, the transducer (II) will automatically deactivate, insuring accurate treatment time for the wound size selected. NOTE: IT IS IMPORTANT TO MAINTAIN A 0.5 TO 1.5 CM (0.2 - 0.6 INCHES) DISTANCE FROM THE LEADING EDGE OF THE APPLICATOR (12) TO THE WOUND AT ALL TIMES TO MAXIMIZE THERAPEUTIC EFFECT. 6 7 8 11 8 17 10 Locking mechanism is in the “locked” position and can not be reused. 16 28 Rotate the Celleration MIST Therapy Saline Bottle (10) in a clockwise direction to stop the flow of saline. There may be saline remaining in the bottle. This is normal depending upon the size of the wound selected. With the system power off (3), remove the Applicator (8) from the Treatment Head (11), place the Transducer (9) into the Transducer Cradle (14) and discard the Applicator (8) appropriately. Do not remove the applicator until the treatment has been completed. The applicator has an integrated mechanical locking mechanism that prevents reuse or re-engagement to the transducer once removed. PREPARATION AND CLEANING OF MIST THERAPY® SYSTEM Clean the MIST Therapy System prior to and after each treatment session with the Power Button (3) in the “off” position. 1 2 14 2 13 CAUTION: CELLERATION MIST THERAPY SALINE BOTTLE (10) AND APPLICATOR (8) ARE DESIGNED AS SINGLE PATIENT-USE DISPOSABLE UNITS TO AVOID CONTAMINATION AND SHOULD NOT BE RE-USED BETWEEN PATIENTS OR RETAINED FOR FUTURE USE. 9 22 Prior to treatment use the first germicidal wipe to clean the system. First, wipe the generator (2) and cradle (14). Then wipe the transducer cable (22), transducer handle (9), and then proceed to wipe the transducer tip (13). Do not sterilize the treatment head (11) with steam, ETO, or cold sterilants. After completion of the MIST Therapy treatment, discard the single-use disposable applicator and use the second germicidal wipe provided to repeat the cleaning process as described in step one.

SUMMARY OF CLINICAL RESULTS FOR LABELING CLINICAL TRIAL EFFECTIVENESS RESULTS This primary objective of the prospective, randomized, controlled clinical trial was to compare the incidence of complete wound closure achieved among chronic diabetic foot ulcers receiving MIST® Therapy in relation to SHAM control by or on week 12. Complete wound closure was defined as full epithelialization without drainage. After a wound was initially considered healed, all patients were scheduled for a return visit one week later to confirm wound closure.The confirmatory visit date was used as the official closure date for the purpose of this analysis. The incidence of index ulcer closure within 12-weeks according to treatment group among 63 evaluable patients is presented in the following table. Thirty-five point five percent (11/31 patients) of the diabetic foot ulcers treated using the MIST treatment were found to close within 12 weeks of treatment, while only 12.5% (4/32 patients) of the foot ulcers in the SHAM treatment group were found to close within the same treatment period (p = 0.032). Incidence of Index Ulcer Closure Status by Treatment Group MIST (n=31 pts) Closure Closed Not Closed Total Control (n=32 pts) Total (n=63 pts) No. % No. % No. % 11 20 31 35.5 64.5 4 28 32 12.5 87.5 15 48 63 23.8 76.2 p-value = 0.0322; Chi-Square Test. The following figure displays the survival curves using Kaplan-Meier product limit estimates of the time-to-closure for both treatment groups. The difference in time to closure observed between the two treatment groups was found to be statistically significant (Log-rank p=0.0090; Wilcoxon p=0.0116) with at marked separation between the two survival curves occurring at the fourth week of treatment. This significant difference remained after controlling for the possible confounding effects of age, gender, baseline area of the index ulcer, use of off-loading device, percent of visits where debridement was performed, intensity of debridement, chronicity of the index ulcer at baseline and investigational center (p=0.0061). Survival Analysis of Closure Status by Treatment Group PL-61000 Rev. A, 12/09 ©2009 Celleration®, Inc. ADVERSE EVENTS The MIST Therapy® System has been evaluated in four clinical evaluations involving 263 patients with a variety of wounds including: recalcitrant pressure ulcers, chronic lower extremity leg and foot ulcers and diabetic foot ulcers. Among these, a prospective, randomized, controlled clinical trial was conducted to evaluate the safety and effectiveness of MIST Therapy System in relation to SHAM control when added to standard-of-care when used in the treatment of chronic diabetic neuropathic foot wounds. A total of 133 patients presenting with diabetic neuropathic foot ulcers were enrolled into the study. This primary safety objective of the study was to compare the incidence of adverse events among patients receiving MIST in relation to SHAM control through the 12-week treatment period. A total of 143 adverse events were reported among the 133 patients, (with at least one adverse event being reported for 45 of the 70 (64.3%) MIST patients and 40 of the 63 (63.5%) SHAM control patients (p = 1.0, Fisher’s Exact Test)). No significant differences were found in the incidence of any of the adverse events between treatment groups (p>0.05). In addition to the incidence of adverse events, this clinical trial also evaluated the severity, device relatedness and seriousness of the events. No statistically significant or clinically important differences were identified between the MIST treatment group and the SHAM control group in the incidence, severity, device-relatedness, or seriousness of adverse events.
